Hello, justjoans,

Absolutely! A lot depends on the style and modern look you’re going for - here’s an example from Rustica - https://rustica.com/high-sierra-barn-door/

Also, consider the door slide hardware as well as the finish, materials, actual door, and roller design - these will all play in to help you achieve the modern look you're targeting.

Finally, clearly there are many examples on houzz itself - still, here’s an article you might find helpful as well. https://www.google.com/amp/s/www.dwell.com/amp/article/modern-sliding-barn-doors-3cc55f39

Enjoy the day!
